clean the starter button and all the other handlebar switches. put some seafoam in the crankcase and run the engine for a few minutes then do an oil change, the seafoam should get the gum off the starter clutches. most older Honda's solenoid will rattle when you shake them so take yours off an see if it doesn't the solenoid is sticking, sometimes they can be freed by smacking them on the bottom with a hammer

Mechanic (Daniel) texted me this morning & said it locked up again. He has tested the battery good several times with a fancy digital battery tester but now the battery failed the test so he is going to replace the battery. More to come when it is fixed. (for good)
